I met my brother there this morning, he managed to get a zinc and couple memorials, I got a 68S memorial (we don't get that many S mintmarks here in Michigan) and a neat cast iron cap gun, it's a Kilgore Presto. It's the first complete cast iron toy that I've found. I also found shotgun shells, pulltabs, foil and your normal general junk. I did find a bunch of heavy gauge copper wire cut in about 6 inch pieces but there was about 8 of them in a small area and I was just getting multiple high readings and didn't know what to think.
